Shown is the demography of the female study population used in the microarray study. No statistical significance was found when ages of smokers and non-smokers were compared (see results). Also shown are the nicotine and cotinine levels for each subject (see methods).
* 11Sm and 12NS represent repeat sampling of subjects Sm28 and NS22, respectively. (cau, Caucasian; his, Hispanic; ND, not detected)
